A systematic review of the concept of self-regulation in infants between 0 and 36 months in Latin America.

This paper aims to identify how cognitive and emotional self-regulation (SR) processes in infants from 0 to 36 months are defined within the Latin American academic context. A systematic review based on the PRISMA methodology was implemented to review the conceptual and operational definition of SR, the type of study, the country of origin of the authors, and the reference to the adequacy of the research to the specific cultural context of Latin America. Twenty-two papers that met the selection criteria were selected. The study identified four types of conceptual definitions for SR, each associated with different constructs or sets of constructs: executive functions, temperament, the integration of executive functions and temperament, and physiological homeostasis. These definitions were based on mainstream approaches to SR rather than being specific to the Latin American region. The study also found compatibility between the sample and some observed trends. On one hand, there was an underrepresentation of the Latin American population in high-impact publications on the subject. However, from 2010 to the present, there is evidence of growth in publications on SR in the analyzed sample. On the other hand, the sample also indicates a disparate representation of the countries of Latin America and the Caribbean in existing publications. Finally, concerning the adaptation to the cultural context of the research, a small number of studies addressed this variable in a specific and significant way. However, even in these cases, the approach is based on models and hypotheses that are limited to understanding the Latin American region's cultural, socioeconomic, and demographic diversity.

Multiple calcifying hyperplastic dental follicles: a major diagnostic consideration in multiple pericoronal lesions - report of two cases.

BACKGROUND: Pericoronal radiolucent lesions are a common radiographic finding, but it is rare that they occur in multiple forms. Multiple calcifying hyperplastic dental follicles (MCHDF) are entities with few cases described to date; nevertheless, they appear to have a very particular phenotypic pattern. CASES PRESENTATION: Case 1: A 10-year-old male was evaluated radiographically, revealing four impacted canines, each accompanied by unilocular pericoronal radiolucency. Case 2: A 16-year-old male was planning orthodontic treatment; following his radiological evaluation all third molars were found to be accompanied with pericoronal radiolucencies. Enucleation, and third molar removal along with the pericoronal tissue were the respective treatments. Microscopically, in both cases, the specimens shown odontogenic epithelium, and type I and II calcifications in the hyperplastic follicles, all these characteristics were consistent with MCHDF. CONCLUSION: Although MCHDF are a rare entity, they must be considered in the differential diagnosis of multiple pericoronal lesions. Under the light of the current evidence, the histological findings may be relatively heterogeneous, but their integration with both the clinical data, which are apparently particular, and with the radiographic characteristics, can lead to a definitive diagnosis.
